Yes,  I had  the  same  problem.  And  it doesn't  help  to  change  the
permissions again. (Except you do it with a cron job. But this is ugly!)
Especially bad is the problem if you use cnews...

What  I did: I simply set the suid bit  of df. But setting a suid always
worries me... Any better solutions out there?

Also  strange: Since I  installed the  MOTD.app multi-volume  disk copys
don't work anymore!! Neither in a net nor at a single user station. 

When will 3.1 be out?

	Gerhard.
